Who can tell me which flange standard to choose for an external pressure of 14 MPa and a nominal diameter of 400?
Thread Content
As the title suggests, who can tell me which flange standard to use for an external pressure of 14 MPa and a nominal diameter of 400? The range specified in JB/T4700~4707 for \"Pressure Vessel Flanges\" is 0.25~6.4 MPa, while the pressure range specified in HG20592~20635 for \"Steel Pipe Flanges, Gaskets, and Fasteners\" fits this range exactly. However, the nominal diameters of various types of flanges exceed this range. I would be very grateful if anyone could provide an answer
It seems there was a post like this a couple of days ago; if there’s no standard, why not use custom flanges? Just do the calculation.
Flange outer diameter 705, center hole 616–9115.1 available
It is designed to be non-standard, and then calculations are carried out!
This one is a bit tricky; generally, flanges are designed to withstand internal pressure, while for external pressure, even when using standard flanges, calculations are still necessary
